Download or read book An Analysis and Design Optimization of the Log periodic Dipole Antenna written by Charles J. Drane and published by . This book was released on 1976 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximate representations for current and charge distributions along each dipole of a log-periodic dipole antenna are derived. The special mathematical forms assumed by these representations are chosen to be particularly compatible with the set of integral equations that the representations must satisfy. An attractive attributes is their ability to handle the rapid variations in charge that often exist near the driving points and ends of the dipole elements. This ability to accurately predict how charges are distributed can be essential to precise estimates of the maximum voltage gradient on the antenna, and is critically important when the antenna is to be designed for high-power applications.

This book was released on 2017-10-03 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights technology trends and challenges that trace the evolution of antenna design, starting from 3rd generation phones and moving towards the latest release of LTE-A. The authors explore how the simple monopole and whip antenna from the GSM years have evolved towards what we have today, an antenna design that is compact, multi-band in nature and caters to multiple elements on the same patch to provide high throughput connectivity. The scope of the book targets a broad range of subjects, including the microstrip antenna, PIFA antenna, and the monopole antenna to be used for different applications over three different mobile generations. Beyond that, the authors take a step into the future and look at antenna requirements for 5G communications, which already has the 5G drive in place with prominent scenarios and use-cases emerging. They examine these, and put in place the challenges that lie ahead for antenna design, particularly in mm-Wave design. The book provides a reference for practicing engineers and under/post graduate students working in this field.

Download or read book Frequency Independent Antennas written by Victor H. Rumsey and published by Academic Press. This book was released on 2014-06-28 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frequency Independent Antennas provides a reasonably complete coverage of frequency independent antennas from its inception until the middle of 1965. Most of the contents have not previously been published, except in scattered journal articles, and some are original. The first six chapters are written at a fairly easy level—about the level of a beginning graduate student or the more advanced undergraduate. The last two chapters, which deal with solutions of Maxwell's equations, are at a somewhat higher level. The book opens with a discussion of some fundamental ideas about antennas. It shows how typical measurements can be understood in terms of classical electromagnetic theory: in other words, how to make sense of measured data, how to set up apparatus to get meaningful data, and how to test their significance. Separate chapters follow on the features of frequency independent, plane-sheet, spiral, and log-periodic antennas. Subsequent chapters discuss how the periodic structure theory provides a way of understanding the peculiarities of frequency independent antennas; and solutions of Maxwell's equations for idealized spiral and idealized sinusoidal structures.

Available in PDF, EPUB and Kindle. Book excerpt: Nonmetallic electroconductive textiles, unlike metals, offer flexibility, durability, moldability, and lightweight attributes. A brilliant quality of these textiles is the capability to alter conductivity through various external stimuli (e.g., strain, torsion, pH, humidity) to suit a specific application such as sensors, heating garments, EMI shielding, energy harvesting devices, and wearable electronics. Based on these concepts, Advances in Electrically Conductive Textiles: Materials, Characterization, and Applications has been structured into three main sections. Section I contains chapters discussing the various preparation methods of electroconductive textiles, Section II contains chapters on their characteristics and features, and Section III details the end-use applications and sustainability of these textiles. - Explores strategies and methods in the development of electroconductive textile composites - ?????Investigates features of nonmetallic conductive textiles prepared from graphene, conductive polymers, MXene, and carbon nanotubes - Examines the application of electroconductive textiles for heat generation, EMI shielding, sensors, antimicrobial, filtration, energy storage, energy harvesting, and smart textiles

Available in PDF, EPUB and Kindle. Book excerpt: Techniques based on the method of modal expansions, the Rayleigh-Stevenson expansion in inverse powers of the wavelength, and also the method of moments solution of integral equations are essentially restricted to the analysis of electromagnetic radiating structures which are small in terms of the wavelength. It therefore becomes necessary to employ approximations based on "high-frequency techniques" for performing an efficient analysis of electromagnetic radiating systems that are large in terms of the wavelength. One of the most versatile and useful high-frequency techniques is the geometrical theory of diffraction (GTD), which was developed around 1951 by J. B. Keller [1,2,3]. A class of diffracted rays are introduced systematically in the GTD via a generalization of the concepts of classical geometrical optics (GO). According to the GTD these diffracted rays exist in addition to the usual incident, reflected, and transmitted rays of GO. The diffracted rays in the GTD originate from certain "localized" regions on the surface of a radiating structure, such as at discontinuities in the geometrical and electrical properties of a surface, and at points of grazing incidence on a smooth convex surface as illustrated in Fig. 1. In particular, the diffracted rays can enter into the GO shadow as well as the lit regions. Consequently, the diffracted rays entirely account for the fields in the shadow region where the GO rays cannot exist.
